Help, hardware engineer assistant and medical equipment sales job which I choose?

Suggest you go to do sales, hardware engineering competition is fierce, girls do not have much advantage, maybe not out of it is also possible, sales company strength, food and accommodation, as long as you do not jump ship, a few years can do very well, girls are also more suitable for sales, since the hardware is not confident should be avoided, there are some things have to give up in order to have gained, purely personal opinion, more and the family to discuss their own decisions!
